That hilt form on the gold keris shown by Rasdan -- I've seen it a similar type on Nias 'keris'. Nias 'keris' is not really a keris. The sheath has a elongated sampir, which I believe is supposed to represent oxen ears, while the blade can be a sewar or golok type of blade, mounted on a hilt like this.

But this gold keris is dressed new. Traditional aesthetics and rules may not apply. The "horse hoof" hilt is typically found on keris panjang, anak alang, and on Minang kerises -- those small luk blades.
